There's nothing that says that two air particles that start together at the front edge of the wing and split up have to arrive at the tail edge of the wing at the same time.
So why would it be that the air on top of the wing has to go faster than the air below the wing?
- deciplex 11y agoThe idea is that the wing is slicing through still air, so the molecules arrive back at the same spot much like you'd expect a slice of cheese to line back up with itself after cutting it. Friction on the surface of the wing means this isn't quite going to happen, but that's the idea.
- tghw 11y agoAgain, this assumes the air is already connected to the air around it in the same way cheese is. You can't lift a layer of air and have it connected to the air it used to be connected to. Likewise, you don't have turbulence in cheese. There's a significant difference between solids and fluids.

This is one of the fallacies that are explained in the best reference I know about this subject: http://www.av8n.com/how/ http://www.av8n.com/how/ It's even illustrated in the title picture... ;-)
